On March 19, 2021 a volcano erupted in Iceland that captured the imagination of people from all over the world. It also changed the lives of April and Martin, independent filmmakers living in an apartment in New York City. Like many of us they were coming out of a long winter dealing with covid - 19. This eruption spawned an idea for their next film. They decided to travel to Iceland to film the eruption and gather stories from the remarkable people who live with the joys and challenges of volcanic eruptions right in their own neighborhoods! Find out how April and Martin created this powerful film.

You can find out how to watch the film at fireandiceland.com. I would love to hear your reactions to the film. You can leave a comment on our website or email me at [email protected].

Nature Guys is proud to say that this is our 200th episode! Our first episode was released in October of 2016. If you are a long time listener you know that my dear friend Bill was my only co-host until August of 2020. If you are new to the show, you can listen to my tribute to Bill on the episode titled “Our Friend Bill” released on September 1, 2020. Nature Guys has not only survived Bill’s loss but thrives thanks to the contributions of many people both on air and off. Special thanks to Gia, Greg and Charles – top notch naturalists who have taken the time from their busy schedules to help me create multiple amazing new shows. On this 200th episode I wanted to play an old Bill and Bob show. I was debating which episode to use when I got an email from Eve Bishop. Eve has a wonderful new four part podcast called Deer Humans. Tune in to hear Eve explain this in her own words followed by the Nature Guys podcast on white tailed deer originally released on October 10, 2017.
